Screen Paging and FTP

Using the standard ftp program, is there a way to page the screen? For
instance, if I'm listing a _huge_ directory, is there a command which
provides an equivalent function to less or more, since neither of which
seem to function in ftp?
I've checked the ftp man page, as well as Linux in a Nutshell. If the
answer is in either of these sources, it has escaped me.
